When primary current 23 flows in the shutter circuit 4 in a state that the shutter dial 20 of the camera is set to AUTO and linked with AE mechanism, a microprocessor 11 immediately detects proper item of information 17 such as aperture, shutter speed, warning of over and under-exposure etc. converts it to analog in a form close to voice and reproduces it by a speaker 13.

Description

[Detailed Description of the Invention] This invention has the following features: (I) A shutter with a voice recognition device that allows the shutter of the camera to be released in response to a voice command; (II) A synthesized voice notification device for shooting information that can be heard with the ears; (III) A well-composed photograph of a person can be taken. a face position and composition display device; (IV) a zoom single-lens reflex camera with a lens parallel to the camera body;
This invention relates to four inventions.

(I) Shutter with voice recognition device Conventionally, camera shutters were push-button type, so camera shake was unavoidable. It is said that the majority of photo mistakes taken by beginners are due to camera shake.

This invention eliminates the above-mentioned drawbacks of the prior art.
To provide a shutter with a voice recognition device that causes no camera shake.

FIG. 1 is a block diagram showing a schematic configuration of the first invention.

A microphone (2) that converts audio into audio signals is built into the bottom of the camera (1), and the audio recognition device (6) connected to it has a filter that analyzes the frequency of the audio signal.
Analyze the vowel sound pattern of the specified voice command (18), store it in the LSI (3), and send it to the camera (
1) and issue the same voice command (18), the LSI
As soon as it is recognized that (3) is the same sound pattern, an electric current (23) is instantly applied to the shutter circuit (4) of the camera (1).
flow and activate the shutter mechanism (5).

Microphone (2) is a LOW, unidirectional microphone that is only sensitive to conversations or whispers coming from within a few centimeters of the camera, and is designed to prevent the shutter from malfunctioning due to "prank voice commands" from a distance. do.

In addition, in order to be able to take pictures of ourselves, the microphone (2) is equipped with a high-sensitivity switch (7) so that the shutter (5) can be activated by a voice command (18) from around 3 meters.
may be provided.

Specify the voice command (18) as around two syllables, such as "cheese" or "satchi", and use the long vowel "ee".
It is also possible to have the LSI (3) memorize only the voice patterns such as ``Kimi'' and ``Mitchie'' that have two consecutive vowels ``I'' in order to prevent malfunctions.

The effects of this invention are as follows: (1) Since the shutter is released by a voice command instead of a push button, no camera shake will occur even if the camera is small and light, or even if a zoom or telephoto lens is attached to it.

(2) Humans can work faster, easier and more reliably with their mouths than with their fingers, so in the case of snapshots, it is easier to capture the ``decisive moment'' quickly and accurately.

(3) If the automatic winder is linked to the voice-instruction type shutter of the present invention, quick shooting performance will be improved.

(4) When a person makes the sound ``I-gyo,'' the muscles in both cheeks rise and they smile. If you ask everyone to say ``Mitchie'' when taking a group photo, the photo will have everyone smiling. At this time, if the voice command (18) is also "Mitchie", the shutter will be released at the right time with the chorus.

(5) Voice commands (18) can be specified according to needs.

For example, someone who prefers quick photography might use ``Kimi,'' someone who primarily takes portrait photos might use ``Mitchie'' or a nickname for a family member or a popular star, and someone who primarily takes landscape photos might use ``Kirei.''

(6) The voice command (18) is short, about two syllables, and instead of recognizing it as is, it memorizes only the voice pattern of the vowel among the syllables, which has a large change in sound frequency and is easy to catch. Fewer memory elements are required, resulting in lower cost.

(II) Synthetic voice reporting device for photographic information In the past, people who were obsessed with taking pictures or beginners would press the shutter suddenly, overlooking the information system displayed in the viewfinder, and not being able to take full advantage of it. Additionally, some cameras had difficulty reading data in dark locations.

Also, when shooting in a dimly lit room or using an ultra-wide-angle lens, the image of the subject seen through the viewfinder was so dark that it was difficult to tell whether it was in focus or not.

This invention eliminates the above-mentioned drawbacks of the prior art.
The purpose of the present invention is to provide a reporting device for photographing information using synthesized voice.

FIG. 2 is a block diagram showing the general configuration of the second and third inventions, a partial sectional view of the second invention, and a front view of the third invention.

First, set the shooting information (17) to "over", "1000", "500", "250" for aperture priority AE shooting.
...such as "30" and "under", shutter speed, shutter speed out-of-link warning, flash charging completed or not, aperture and other information in the case of shutter speed priority AE, shutter speed and aperture, and other information in the case of program AE, etc. Also, when the focus is correct, click "In focus" or "OK".
etc. Or include a shooting distance scale that works with the lens. The characteristics of the input waveform and frequency of the audio to be recorded are 0.
Change it to a digital signal of 1 and 1 and memorize it in the memory (8), then turn the camera's shutter dial (20).
set to A (auto), and while linked to the AE mechanism (21), press the shutter button (22) slightly, issue the primary voice command (181) into the microphone (2), or press the camera A new information button at the top (
When the primary current (231) flows through the shutter circuit (4) by pressing 19), or when the lens (14) is focused manually or by autofocus, Like a reflex camera, the light that passes through the half mirror part of the first mirror (151) and is reflected by the second mirror (152) is reflected by the film (1
When the image was focused on the focus sensor (9) placed on a surface equivalent to 6), the focus sensor (9) sensed it and converted it into an electrical signal, causing a current (23) to flow through the circuit (10). At times, the microprocessor (11) instantly searches for the corresponding item in the shooting information (17), and the digital-to-analog conversion circuit (12) converts the digital signal into an analog form similar to audio, and adjusts the volume. This is a device that reports photographic information in synthesized sound to be played back on a speaker (13) that can be used.

In addition, if the shooting information (17) is reported as "over" or "
If the camera is unsuitable for shooting, such as "under-under", the shutter circuit (4) will be turned off and the current will not be generated even if you press the shutter button, unless you close down the aperture, use a flash, or correct the condition to allow shooting. (23) may not flow and the shutter mechanism (5) may not operate. The effects of this second invention are as follows: (1) People with poor eyesight, rash people, or troublesome people are not good at looking at the conventional viewfinder display, but they can easily listen to information.

(2) In the case of the system in which the shooting information is heard with the first voice command and the shutter is released with the second voice command, there is no need to overlook the display in the viewfinder as in the past.

(3) Conventionally, due to this oversight, the user pressed the shutter even when it was inappropriate to take a picture and failed, but this invention avoids this failure because it is unprecedented.

(4) If the shutter circuit (4) is automatically turned off in the case of a notification of unsuitability for photographing, failure can be completely prevented.

(5) Listening to the display in the viewfinder is faster, easier, and more reliable, which improves quick shooting.

(6) When exposure becomes fully automatic, such as with Program AE, data such as shutter speed and aperture cannot be determined, but it is easier to record data if you listen to it.

(7) In the past, focusing was difficult for people with poor eyesight or in dimly lit places, but if you hear words such as "focusing," you can take pictures that are in focus and improve your ability to take quick shots.

(8) In the Pentax ME-F, the electronic sound for focusing is a little quiet and the sound is difficult to hear in noisy places, but the speaker (13) of the present invention allows you to adjust the volume depending on the time, place, and situation.

(III) Face position and composition display device Conventional cameras have become stupid in terms of exposure, but cameras for beginners are equipped with wide-angle lenses with a deep depth of field to prevent blur and out-of-focus, but this is more than meets the eye. The subject appears small in the photo, and most beginners have a habit of bringing the face to the center of the photo frame, perhaps due to an illusion, when taking portraits, so unnecessary objects appear large in the top half of the photo and on the left and right sides. The result was a photograph with a poor composition.

It is an object of the third invention to provide a facial position and composition display device that eliminates the above-mentioned drawbacks of the prior art and allows anyone to take well-composed photographs of people.

The primary current (231) is applied to the shutter circuit (4) in Figure 2.
, an oval or cross-shaped face position composition mark (25) symbolizing the face is placed outside the field of view in the viewfinder (24), around 1/4 to 1/3 from the top of the vertical or horizontal screen. The top, bottom, or center point of the spot you touched lights up or flashes with the LED.

(1) The habit of beginners to bring the subject's face to the center of the screen is based on the difference between vision and lenses, so it is difficult to overcome by simply saying it, but with this invention, it is possible to release the shutter. Since the LED lights up every time just before the photo is taken, ``Due to the composition, the face should be raised higher than the center of the screen.''
I can remember that.

(2) Conventional camera instruction manuals only described hardware, but with this invention, it is now possible to include software that explains the importance of composition in photography, along with professional photo examples. .

(3) If beginners can take better-composed photos, the camera will naturally become popular as a good camera, and sales will increase.

(IV) Single-lens reflex camera for zooming This invention relates to a single-lens reflex camera for zooming in which a long mirrored copper lens does not get in the way.

Previously, when attaching a zoom or telephoto lens to a 35mm camera, the long mirrored copper lens protruded at right angles to the camera body, making it bulky and difficult to carry, and there was also the risk of the long lens coming into contact with other objects and damaging it. .

This invention eliminates the above-mentioned drawbacks of the prior art.
The purpose is to provide a highly portable zoom single-lens reflex camera.

FIG. 3 is a sectional view schematically showing the fourth invention.

Place the film surface (16) where the pentaprism (26) of a conventional single-lens reflex camera (1) was, and
) is bent at a right angle by a quick return mirror (15') or a half mirror (15'') to form an image on the film surface (16), and a finder (24) and eyepiece are placed behind the lens (14). By placing the part (27) so that the image is erect, the lens (14) is attached to the camera body (1').
It was installed parallel to the .

In addition, if the camera body is half size or 110,
The lens (14) may be a fixed zoom lens or telephoto lens placed on the camera body, and zooming or focusing may be performed electrically or manually, and the shooting distance may be displayed in the finder (28) according to the focusing. Alternatively, it may be combined with any one of the first to third inventions.

The effects of this invention are as follows: (1) Since the long copper lenses of zoom and telephoto lenses are parallel to the camera, they are more compact than conventional protruding lenses, and the chance of contact damage to the lenses is reduced.

(2) The design will change as the pentaprism will be removed.
Receipt and bulk are also reduced, making it possible to lower the price.

(3) Using electric zooming and focusing makes operation easier, prevents malfunctions, and improves quick shooting performance.

(4) Conventional beginner cameras with wide-angle lenses actually make it difficult for beginners to take well-composed photographs. A camera with a zoom lens that allows for flexible framing allows you to take well-composed photos. But with zoom 35
Millimeter SLR cameras were bulky and heavy due to their effects.

The voice-commanded shutter, which was a major invention, made it possible to create an ultra-compact zoom camera with no camera shake.The above invention made it possible to create a more portable, low-priced camera that even beginners can take well-composed photos. Can be provided in combination.

(5) Although half-size single-lens reflex cameras are not currently available on the market, they should be reconsidered because film and processing costs are halved, and they are more portable. With conventional half-frame cameras, when you look through the viewfinder, the screen is vertical, so you end up taking a lot of vertical photos. The zoom single-lens reflex camera of the fourth invention corrects this problem, and if the camera is held horizontally, the screen will be horizontal.

Traditionally, 35mm film takes at least 12 shots, so half-size film takes twice as many shots, which is 24 shots, making it difficult to finish shooting. If this half-frame single-lens reflex camera became popular, it would be helpful if 35mm film with around 6 exposures became available on the market.
